Rice alcoholic beverages, cheongju and beopju, which are recorded in "Koryodokyung", "Koryosageolyo", and "Koryosa", were used in national and royal ceremonies, and yakju was used in the Palgwanhoi ritual. In the late $11^{th}$century, King Munjong imported hwaju and haenginjabeopju from the royal family of the Song Dynasty. Alcoholic beverages in the early $12^{th}$century included the medical use for kings, such as gyehyangeoju, which the Emperor of the Song Dynasty sent to King Yejong, baekjainju, which was sent to King Myeongjong for his health, and yangju, which is goat milk fermented alcohol from the nomads in the northern regions. In the early$13^{th}$ century there was also dongrak, which is a horse-milk fermented alcohol, grape wine sent from Yuan to King Chungryeol in the late $13^{th}$ century, and sangjonju, a type of special cheongju sent from Yuan in the early $14^{th}$ century. Baekju from Yuan was recorded in oral traditions, which suggests that soju, which is distilled cheongju, was consumed in the late $14^{th}$ century. Gold and silver wares for alcoholic beverages had important political, social, and economic meanings as national gifts to other countries and internally as the king's royal gift to his subjects. In the late $14^{th}$ century, soju was prohibited, and the use of gold and silver wares for alcoholic beverages was banned at the same time. This study examined the historical characteristics of the use of traditional rice alcoholic beverages, the emotional preference for foreign alcoholic beverages, and the gold and silver wares used for alcoholic beverages Koryo Dynasty.

Lactic acid bacteria are microorganisms that are closely associated with human and/or animal environments, and are categorized as generally recognized as safe (GRAS) organisms due to their ubiquitous appearance in foods and their contribution to the healthy microflora of mucosal surfaces. This study was performed to isolate and identify lactic acid bacteria with antagonistic effects against food-borne pathogens. A total of 3,000 acid-producing bacteria were isolated from infant feces, cattle feces, goat feces, dog feces, pig feces, vaginal tracts, vegetables, fruits, Kimchi, Jeotgal, fermented sausages, raw milk, cheese, yogurt, Cheonggukjang, Meju, and Makgeolli cultured on MRS agar with 0.05% bromocresol purple. For the isolation of bacteriocin-producing bacteria, the diameter of the clear zone was measured on MRS agar plates. Twenty-six isolates exhibited strong antibacterial activity against indicator strains such as Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella enterica serovar Enteritidis. Lactic acid bacteria were identified as Enterococcus faecalis, Enterococcus faecium, Enterococcus hirae, Lactobacillus acidophilus, Lactobacillus amylovorus, Lactobacillus curvatus, Lactobacillus plantarum, and Pediococcus acidilactici by 16S rDNA gene sequence analysis. The results of this study suggest that the isolates could be used as potential probiotic starters for functional food applications.
